Effect of mycorrhizal strains in the quality of the plant Calophyllum antillanum Britton in nursery

Abstract

The work was carried out in the Municipal Agricultural Interprise in the municipality of Moa in the province of Holguín, from january to May the 2016, with the objective to evaluate the effect of different mycorrhizal strains on the morphological parameters of the species Calophyllum antillanum, under nursery conditions. The treatments that were used were: T₁- Soil / Glomus cubense in proportion 9: 1, T₂ - Soil / Funneliformis moseae in proportion 9: 1, T₃ - Soil / Rhizophagus intraradices 9: 1 and T₄ - Control (Worm Humus in proportion 5: 1 "Five wagons of soil and one of organic matter"), through a completely randomized design. 100 plants were used for each treatment, evaluating 25 in each of them, at 30, 60, 90 and 120 days after germination. The statistical package STATGRAPHICS Plus 5.1 was used. The results indicated T₂ -Suelo/Funneliformis moseae en proporción 9:1, with the best results in the morphological parameters: plant height, stem diameter, leaf number, dry leaf mass and root, morphological attributes of the root system: long root length, number of primary roots and secundary, morphological index of plants: slenderness (H / D), shoot part ratio - RPA / RPR and Dickson quality. For the production of good quality postures T₂ is also the most economically feasible, since the total expenses are 0.34.
